Let $i_{E}, i_{C}$ and $i_{B}$ represent the emitter currently the collector current and base current respectively in a transistor Then:

$i_C$ is slightly smaller than $i_E$

The correct answer is Option (1) → $i_C$ is slightly smaller than $i_E$

The emitter current $(i_E)$ is -

$i_E=i_C+i_B$

$i_C$ = Collector current

$i_B$ = Base current

∴ $i_C$ is smaller than $i_E$
